This is a top cap base on EVplug female type 2 connector (https://www.amazon.fr/gp/product/B08Y7PNTGY/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1).

It's compact and specially useful for electric Motorcycles.
Combine with electronic like EVSE (https://www.evracing.cz/en/evse-w16/) you can make a 16A /3kw compact charging cable for EVs.

Recommended to print in ABS (I used TitanX)
Do not use PLA
Does not comply with the CE standard (but works fine ;-))
